  100% {
    transform: rotate(-405deg);
  }
}
@keyframes icon-line-tip {
  0% {
    width: 0;
    left: 1px;
    top: 19px;
  }
  54% {
    width: 0;

  }
  100% {
    width: 25px;
    left: 14px;
    top: 45px;
  }
}
@keyframes icon-line-long {
  0% {
    width: 0;
    right: 46px;
    top: 54px;
  }
  65% {
    width: 0;
    right: 46px;
    top: 54px;
  }
  84% {
    width: 55px;
    right: 0px;
    top: 35px;
  }
  100% {
    width: 47px;
    right: 8px;
    top: 38px;
  }
}

All you need to do is to add a :key to our animated element and to increment the key every time a user clicks on the replay button. Yup, that's it!

  <div
  id="app"
  >
    <div class="success-checkmark" :key="replay">
      <div class="check-icon">
        <span class="icon-line line-tip"></span>
        <span class="icon-line line-long"></span>
        <div class="icon-circle"></div>
        <div class="icon-fix"></div>
      </div>
    </div>
    <button @click="replay++">
      Replay
    </button>
  </div>

new Vue({
  el: "#app",
  data: {
  replay: 0
  },
})
